These whitening strips were my first I've ever used, and are still going strong many months later. I have bought another set just to keep up. These aren't going to give you a bleaching white smile, but will get some nice shades of white that are noticeable and look good on a smile.

[This review was collected as part of a promotion.] I absolutely love these Whitening strips from crest. They’re very easy to use and very comfortable to wear. Also my teeth didn’t get sensitive with these which is great and the packaging was easy to use. Overall, I would highly recommend these strips and they work fast and work really well. If you have a special occasion, and you would like to whiten your teeth, these are the whitening strips for you!

Not terrible at whitening, it does a bit but this are very, very intense and strong. I would not recommend for those with sensitive tether or gums as it made mine hurt for days. Definitely a more “affordable” item for whitening your teeth but I prefer to use something a little more gentle.

[This review was collected as part of a promotion.] I have used crest white strips throughout the years, and I think the professional effects are the most effective I have ever used. I noticed a difference in the whiteness of my smile in 3 applications. I also really like that one package comes with two weeks worth of white strips. The only complaint I have is that I can only use them once every few days because they make my teeth too sensitive to heat and cold.

These are my favorite of the Crest White Strips lineup! They work fast & have a long lasting effect. I've been hooked on them for awhile & recommend them to friends and family often! Some home whitening kits can leave your gums irritated & red, but I've never had that problem with these strips.

I didn’t see as significant of a change after using these as I did the 1 hr strips. I did use these for a while, but haven’t repurchased because I just felt like I had found other products that would show an immediate, lasting difference that built over time where these just didn’t do that.

I try to keep my teeth white, I drink coffee and tea so I have stains. I have used these on and off for several months and I think my teeth are whiter because of them. They take about 2 weeks of use to see a difference and they make my teeth very sensitive due to the constant use and bleach as an ingredient.

My teeth would be much more yellow if I didn’t use this because I drink coffee daily as well as tea and wine. These can definitely make your teeth sensitive though so I use these only when I notice my teeth are trailing behind where I like them to be in terms of whiteness.

This is my third usage in 10 years. I am happy each time. I also am blessed with unnaturally white teeth and the contrast to my skin colour helps :) Most people make the mistake of NOT using the strips consecutively and therefore the results are not as great.

I love this product! As a practicing dental hygienist, I wanted to try these out so I could recommend and give my personal experience to patients. I’ve been wearing them once daily for about 2 weeks now and I am super happy with the results (and very little sensitivity)!
